Detailed Description

A namespace for utility structures for CUDA.

Function Documentation

malloc()

template<typename T >

void Utilities::CUDA::malloc ( T *& pointer, const unsigned int n_elements )

inline

Allocate n_elements on the device.

Definition at line 84 of file cuda.h.

free()

template<typename T >

void Utilities::CUDA::free ( T *& pointer )

inline

Free memory on the device.

Definition at line 96 of file cuda.h.

allocate_device_data()

template<typename Number >

Number * Utilities::CUDA::allocate_device_data

(

const std::size_t

size

)

Allocator to be used for std::unique_ptr pointing to device memory.

Definition at line 108 of file cuda.h.

delete_device_data()

template<typename Number >

void Utilities::CUDA::delete_device_data ( Number * device_ptr )

noexcept

Deleter to be used for std::unique_ptr pointing to device memory.

Definition at line 120 of file cuda.h.

copy_to_host() [1/2]

template<typename T >

void Utilities::CUDA::copy_to_host ( const ArrayView< const T, MemorySpace::CUDA > & in, ArrayView< T, MemorySpace::Host > & out )

inline

Copy the device ArrayView in to the host ArrayView out.

Definition at line 131 of file cuda.h.

copy_to_dev() [1/2]

template<typename T >

void Utilities::CUDA::copy_to_dev ( const ArrayView< const T, MemorySpace::Host > & in, ArrayView< T, MemorySpace::CUDA > & out )

inline

Copy the host ArrayView in to the device ArrayView out.

Definition at line 147 of file cuda.h.

copy_to_host() [2/2]

template<typename T >

void Utilities::CUDA::copy_to_host ( const T * pointer_dev, std::vector< T > & vector_host )

inline

Copy the elements in pointer_dev to the host in vector_host.

Definition at line 163 of file cuda.h.

copy_to_dev() [2/2]

template<typename T >

void Utilities::CUDA::copy_to_dev ( const std::vector< T > & vector_host, T * pointer_dev )

inline

Copy the elements in vector_host to the device in pointer_dev. The memory needs to be allocate on the device before this function is called.

Definition at line 176 of file cuda.h.
